Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) ...

I am have a slight problem with two recursive functions I wrote: Sine and Cosine. Each function depends on the other (and itself) to compute the value of Sine and Cosine for any value input. I am ...

This article compares two algorithms that compute values of the sine and cosine functions using analytic geometry and the unit circle definition of sine and cosine. One algorithm uses chords on the ...

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core groups—reciprocal, quotient, and Pythagorean—form the foundation. Effective strategies ...

In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has been ...
